Since the events are mutually exclusive (you can't hit a yellow section and 1 section at the same time), we can add the probabilities of both A (hitting a yellow section) and B (hitting a section with a 1).
Thus, the probability of hitting a yellow section or a section with a 1 is
.
Answer:
The answer is a = 7, b = 9, c = 4
Step-by-step explanation:
Rational exponents works as follow: considering , the numerator has the role of the usual, whole-number exponents, while the denominator is the order of the root we want to extract. So, again, the writing means that we want to consider the c-th root of , i.e.
So, in your case, the exponent is nine over four. It means that you want to consider the fourth root of , hence the answer.
